Medium frequency spot welding machine JIDW-800+180

Medium frequency spot welding machine JIDW-800+180

Comparison between medium frequency DC resistance welding controller and AC control

1. When AC current passes through the welding area, it will diverge due to the surface effect. On the contrary, the medium frequency welder outputs DC current with very small ripple
The welding area has a "bunching effect" towards the center. It can concentrate the welding heat and reduce the heat affected zone around the welding point. This feature is particularly important for the welding of multilayer plates and thick plates;
2. The AC welding machine adopts the AC chopping mode, so it has the characteristics of discontinuous current and high current peak, which causes the AC welding machine to weld
It is easy to produce a lot of spatter during the welding process, which will damage the surface of the weldment and bring a lot of work to the manufacturer. The medium frequency DC welding machine outputs continuous DC current, with stable current and high control accuracy. In addition, the bunching effect of DC current ensures that there is little or no spatter during welding.
3. The medium frequency DC controller outputs DC current with very small ripple, without zero crossing effect, so it has irreplaceable advantages in light alloy, heat-resistant steel, precision parts, high-speed seam welding and occasions with high requirements for welding quality.
